hmm... then kawarimi, what were the small scale dust clouds they were falling into originated from?
They would have to hit the ground and THEN the dust would occur... unless I am not understanding you correctly.

As for the trails, yes you are right. The trails do indicate that the shadows were moving inwards. Also you would see the dust cloud dent inwards after the shadows entered it. It wouldnt make sense if it were reversed since the dust cloud would dent outwards if the bodies are being ejected from it.

So now its even weirder. AssertnFailure may be right, and it just might be a weirdly made return of the bodies after being blasted into the air, weird in that bodies seem to be coming from the left and right (relative to us viewers) as oppose to an angle with more vertical. If the screen was rotated 90 it would make a lot more sense. Bouce of the wall? hahaha

When I posted this, i thought it was a dead topic. I thought someone probably brought this up a long time ago and it was answered back then. Guess not.. hehe
